建形修改器

建形修改器使网格物体的面随着时间的推移一个接一个地出现或消失。

默认情况下,面按照它们存储在内存中的顺序显示 (默认为创建顺序). 可以通过从操作搜索菜单 Spacebar 选择在编辑模式中更改面/顶点顺序 排列网格元素 .

Note

使用 Blender 渲染器时,如果网格的材质是光晕而不是标准材质的话,那么逐渐显现的是网格的顶点,而不是面。

选项

起始
创建过程的起始帧
长度
创建物体所用的帧数。
随机
创建物体的面时,顺序随机化。
种子
随机种子。当 随机化 勾选后,修改此值得到不同的“随机”顺序 -- 顺序对一个特定的种子和物体集合总是一样的.
反向
修改器将反向运行,基本上会把它用作“解构”效果。 这对于使一组多个物体逐渐消失很有用。

例子

The Build Modifier is often useful when needing a way to get a large number of items to progressively appear, without resorting to animating the visibility of each one by one. Examples of this include a mesh containing vertices only, which is used as a duplivert emitter, and has the build modifier on it. Such a setup is a workaround/technique for being able to art-direct some semi-random layout of a collection of objects (i.e. leaves/balls forming a carpet of sorts) when doing so with particles is not desirable (e.g. due to undesirable distribution of items leaving random gaps and overlapping in other places).
